Canon EF 16-35mm F2.8L II USM
The EF 16-35mm f/2.8L II USM Lens from Canon is a high performance, water-resistant, ultra wide-angle L-series zoom lens. An f/2.8 maximum aperture is effective in low light situations and offers shallow depth of field focus control. The optical design has been improved to offer better edge-to-edge image quality. In addition, it features 3 high-precision aspherical lens elements, each of a different type: ground, replica and GMo. Its ultrasonic motor (USM) and improved AF algorithms will help the lens to focus faster and quieter. Precise manual focus is supported even in One Shot AF mode and a truly round aperture results in pleasing background blur.

Canon EF 24-70mm F2.8
Spanning a popular and versatile range of focal lengths, the EF 24-70mm f/2.8L II USM is a Canon L-series zoom commonly thought of as the workhorse of lenses. Ranging from wide-angle to portrait length, this lens is also distinguished by its constant f/2.8 maximum aperture to benefit working in difficult lighting conditions and to afford greater control over depth of field. The lens is also characterized by its sophisticated optical design, which includes one Super UD element and two UD elements, which reduce color fringing and chromatic aberrations in order to realize a high degree of color accuracy and clarity. Three aspherical elements are also featured, and minimize distortion and spherical aberrations for improved sharpness. Additionally, a Super Spectra coating has been applied to individual elements to control flare and ghosting for high contrast and neutral color fidelity.

Canon EF 70-200mm F2.8
A workhorse of a lens, the Canon EF 70-200mm f/2.8L IS II USM is an L-series telephoto zoom characterized by its bright f/2.8 constant maximum aperture and optical image stabilization. The fast maximum aperture affords greater control over depth of field and benefits working in low-light conditions while the Image Stabilizer compensates for four stops of camera shake for sharper handheld shooting. As an L-series lens, this 70-200mm also features a sophisticated optical design that uses five ultra-low dispersion elements and one fluorite element to reduce color fringing and chromatic aberrations for improved clarity. Also, a Super Spectra coating has been applied to help reduce lens flare and ghosting for greater contrast and color neutrality.
